Recently, a novel antibacterial fluoride dentifrice containing stannous fluoride and sodium hexametaphosphate (Crest ® PRO-HEALTHTM) was introduced. A digital plaque image analysis (DPIA) technique was used to quantify in situ plaque formation in a population carrying out a phased intervention protocol that included: (1) an initial treatment regimen including toothbrushing with standard sodium ...

Blocks of human enamel were cycled through a demineralization--F-treatment-remineralization procedure and then analyzed for fluoride and the presence of caries-like lesions. Treatments with a sodium fluoride gel (5000 ppm F) increased the enamel fluoride concentration to 6500 ppm F, whereas a stannous fluoride gel (1000 ppm F) increased enamel fluoride to about 1200 ppm F. Although a control tr...

when tc-99m-sulfur colloid was introduced as an ideal liver-spleen agent in nuclear medicine, many other types of colloids followed by different manufacturers. they hoped to find a suitable colloidal agent, contrary to sulfur colloid, which is easy to use, and less sensitive to the low contamination of aluminum ions. one of this type of colloid agents, is tc-99-tin-colloid which is prepared by ...

Cost-effective, abundant, and non-toxic SnS nanosheet semiconductors can be used as water-splitting cells. Herein, a photoanode based on high-purity highly crystalline nanosheets was fabricated. We sodium thiosulfate (Na2S2O3·5H2O) stannous chloride (SnCl2·2H2O) the tin sulfur source materials, in place of SnCl4 H2S gas, respectively, which have been previous studies. This gas-free fabrication ...

BACKGROUND The pattern of contact sensitisation should be monitored in order to detect the changing trend of sensitising allergens. We aim to evaluate contact sensitisation in adults suspected to have allergic contact dermatitis. METHODS This is a five-year retrospective review on contact sensitisation in adults patch-tested with the European Standard and extended series between 2011 and 2015...
